SECTION 2 OVERVIEW

1 Outline

1.1 Usage

Basically, the Colormetry CMU-324HE has been developed as part of a processing system for

boiler water.

The Colormetry automatically and regularly implements the process of sampling the water,

injecting the reagent, stirring and evaluating the result, thereby obviating the conventional

manual procedure.

The equipment has been designed with emphasis on the reliability of the monitoring results.

The manually selectable conditions—for instance, to verify monitoring upon the detection of

hardness leakage—prevent temporary fluctuations from triggering alarms.

1.2 Purpose

The Colormetry CMU-324HE is a device for monitoring water quality. It is not a device for

measuring. The result data cannot be used for inspection or analysis of the water treatment

system.

Usage example:

Monitoring hardness leakage of the water softener

SECTION 2 OVERVIEW

1.3 System Layout

The Colormetry consists of the reagent cartridge (the indicator), reagent indicator mechanism,

monitoring system and feed-water and drain systems.

1.4 Principle

The Colormetry is a device to monitor ionic concentrations in water by applying colorimetric

analysis. In a colorimetric analysis process the ionic and other concentration in water is

monitored by allowing a reagent to react against the target ions and others, and monitoring the

transmissivity of the resultant coloration for light of a specific wavelength. The Colormetry

replaces this process by an electrical monitoring system and automates the entire process.

Other features include the remote alarm output, self check function, and display, as well as the

monitor standby while the water softener is regeneration or the sample water stopped (remote

signal input).

Monitor process is indicated as follows.

[1] Washing and filling the monitor chamber with sample water

The solenoid valve opens, filling the monitor chamber with sample water. The old sample

water remaining in the chamber is pushed out, and the chamber is washed at the same time.

[2] Injecting reagent and stirring sample water

The solenoid valve closes, and the injection pump inject the reagents into the sample water.

The electromagnetic induction coil, activated at the same time, mixes the water and reagent.

The reagent causes coloration of the sample water in accordance with the hardness

concentration of the water.

[3] Monitoring the sample water

The light source is activated to project light into the sample water. The photereceptor

electronically monitors the light transmitted through the sample water. The intensity of the

transmitted light varies, depending on the color of the sample water. These variations are

caused by light absorption in the water, which varies with the color of the water.

[4] Evaluating the concentration and displaying the result

The concentration is evaluated from the monitoring value, and the result is indicated on the

LCD.

1.5 Applicable Water Condition

The Colormetry CMU-324HE monitors the hardness. Use CMU-H2 reagent cartridge.

The reagent may be affected by substances other than hardness.

The equipment cannot measure water of the condensate return tank.

Keep to the following items in an allowable range. If the water condition is not followed, the

equipment may fail to monitor correctly.

Items Allowable range

Fe (Iron) 1.0mg/L or less (*1)

Free chlorine 2.0mg/L or less

M-Alkalinity+ Silica(*3) 500mg/L or less

pH 5.0 ~ 8.6

Zn (Zinc) (*2)

Cu (Copper) (*2)

*1: It is the value measured by adding hydrochloric acid.

*2: The metal ion such as zinc and copper are determined as hardness.

Therefore, the system judges hardness higher.

Pay close attention in case the galvanizing pipe or copper pipes are used.

The metal ion (zinc and copper) is evaluated as 1.5 times the calcium and

magnesium hardness.

(Ex.) hardness: 0.1mg/L

Zinc: 1.0mg/L

Evaluate value: 0.1＋1.0×1.5＝1.6mg/L

*3: Measurement results of this unit is affected by the M-Alkali and dissolved carbon

dioxide gas and silica in a complex manner. Therefore, you must calculate the result

of the following equation is within the acceptable range.

Silica + M-Alkalinity + M-Alkalinity × 11,700,000／10^pH

SECTION 2 OVERVIEW

1.6 Highlights of Features

The Colormetry has the following features:

[1] Monitors hardness leakage automatically

The monitoring process is fully automated, saving a significant amount of work by

eliminating the need for complicated manual procedures.

[2] Requires no periodic calibration

The equipment needs no cumbersome periodic calibrations.

[3] Includes built-in timer

Monitoring period may be set as desired. (e.g. daily between 9 a.m. and 5 p.m.)

Interval for each monitoring may set as desired. (The interval is selectable in 30-minute

increments between 30 and 240 minutes.)

[4] Alarm set point for the hardness leakage

The evaluation ranges are 0mg/L, 1mg/L, 2mg/L, 3mg/L, 5mg/L and up.

[5] Evaluates hardness leakage at higher accuracy

When a hardness leakage is detected, monitoring is repeated a number of times

(concentration anomaly retry; selectable between 1 and 3 times) to prevent a temporary

fluctuation from triggering an alarm. In addition, such an abnormality must be repeated in a

series of monitoring at a preset interval for a number of times (response alarm cycle; also

selectable between 1 and 8 times). When all of these monitoring results indicate a hardness

leakage, it is evaluated that hardness leakage exists and the alarm is issued.

[6] Indicates data on the display screen

The display indicates the evaluated result, and the major cause of system error occurs in

the equipment.

[7] Offers an alarm function

When it is evaluated that there is a hardness leakage, the buzzer sounds. By the remote

alarm output, the alarm signal can be transmitted to a remote location.

Offers a self check function. If a system error occurs in the equipment, a typical cause will

be displayed in the same manner as the hardness leakage

[8] Stores records of hardness leakage

The equipment stores the records of occurrence date and time, evaluated result and

recovery date and time for each of the 5 latest incidents of hardness leakage. The records

may be utilized to analyze the causes of hardness leakage.

SECTION 2 OVERVIEW

13

[9] Requires minimal maintenance

The reagent cartridge may be replaced using a one-touch action. The reagent cartridge

needs no replacement for approximately 4 months in typical applications. (Note that more

frequent replacement may be necessary, depending on the application.)

[10] Compact in design, easy to install

The main equipment is installed easily on a wall.

Installation is a simple process.

[11] About advanced features

・Remote signal input function

The external signal controls whether to perform monitoring or not. This enables to

remotely stop monitoring while the system, which the water softener is regenerating.

・Remote alarm output

The remote alarm output, the alarm signal can be transmitted to a remote location as a

contact output in case that hardness leakage or system error occurs in the equipment.

・Regent cartridge exchange output

This output may be used to transmit to a remote location when a reagent cartridge

needs to be replaced.

SECTION 2 OVERVIEW

14

[12] Data capture tool

Up to 10,000(*1) monitor records (monitored date and results) can be stored in the

Colormetry. Also, by using a dedicated data capture tool installed on the PC (*2), the

monitor record data can be transferred to the PC. However, the Colormetry and PC must

be connected by an RS-232C cable (*3).

*1: Data for almost 1 year can be stored when monitoring at an interval of 60 minutes.

However, if manual monitoring is repeated, or if the monitor interval is set to less than

60 minutes, the data will be stored for less than 1 year. When the number of records

exceeds 10,000, the oldest monitor record data is deleted.

The data is in CSV format. The year-round trend can be managed through graph

creation software such as Microsoft Excel.

*2: Compatible PC OS is Windows® XP 32bit and Windows® 7 32bit.

*3: Use a female 9-pin D-Sub serial straight RS-232C cable (sold separately).

The cable length should be 1 m or less.

NOTE

If power is not supplied to the Colormetry for long periods of time, the internal memory

will be lost, and the record data will be initialized. If you do not intend to use the

Colormetry for a long time, capture the monitor data before cutting off the power. The

standard backup period is a maximum of 7 days in a 25°C environment.

1 Inspections and Preparations before Start up

1.1 Inspection and Preparation of the Surrounding Area Peripheral Equipment

Check the following points before starting operation of the Colormetry.

Make sure no water is leaking from the equipment and from around the piping.

・ Do not start the operation if a leakage is found. Instead, ensure that the main power

breaker is set to the OFF position, and then contact your dealer or MIURA sales office.

NOTE

Water Leakage Countermeasures

Factors such as loose connectors and aging of pipe materials can lead

to water leakage. It is important that drain ditches be setup for the

water treatment equipment and all peripheral equipment.

(In order to prevent water from leaking outside the room or downstairs,

set up a drain ditch that completely encloses the whole equipment,

ensure that the floor itself is waterproof, make the floor slope

downward to the drain port, and take any other necessary steps.)

2 Preparations before Start up

*Check the following items before start up.

Raw water pressure should be 7.1~ 71psi (0.05MPa ~ 0.49MPa).

The sample water collecting point (branching from main piping) to the filter casing assembly

should be within 1m.

If the Colormetry is installed much higher place, it might cause an evaluation error because of the

lack of sample water.

Open the ball valve at the sample water collecting point and let water run into the feed-water tube

2 FUNCTIONS

2.1 Remote Signal Input

2.1.1 Method

Monitoring the stagnant water in the piping may result in an evaluation error or a system

error of the equipment due to the lack of flow. To avoid such errors, the Colormetry provides

the following two methods, which may be used simultaneously.

Method No.1: Monitor start and stop times

The monitor start time [S Start] and monitor stop time [S Stop] settings limit the period

during which monitoring is performed. The provision helps avoid monitoring while water is

not used.

Example: Operation period: 8:00 through 17:00

↓

Set the monitor start time [S Start] at 8:00 and stop time [S Stop] at 17:00

Method No.2: Remote signal input

Connecting the external contact with no-voltage enables to control the Colormetry for

monitoring only while the water softener is turned on, or to suspend monitoring while the

water softener is regeneration.

The purpose of remote signal is to prevent a monitoring while the system, which the

Colormetry is monitoring for, is stopped, such case as the water softener is at the

regenerating period.

2.1.2 Detailed descriptions

The remote signal input may be processed to enable monitoring in either two methods.

[1] The OFF state

[2] The ON state

The two methods are selectable in the setting mode [Set Mode]. Both methods achieve the

same objective (of preventing an evaluation error), though they process the signal

differently.

[1] Monitoring is enabled by remote being turned OFF [S Rte Sgl OFF] (the factory setting)

The OFF state of the remote signal input (the external contact is open) permits

scheduled monitoring after the monitor interval [S Intvl] as preset in the setting mode

[Set Mode].

The monitor interval [S Intvl] may be set in 30 minutes increments up to 240 minutes.

The reagent will last approximately 4 months on the basis of every 60 minutes

monitoring.)

SECTION 4 OPERATION

26

Example: Input regeneration signal from water softer.

When there a water softener contact has the contact which turns ON (closes) during

regeneration, and connecting this contact to the Colormetry, this remote signal

disables scheduled monitoring. When the softener contact turns OFF (open) at the

completion of regeneration, scheduled monitoring is again enabled.

[2] Monitoring is enabled by remote signal being turned ON [S Rte Sgl ON]

The ON state of the remote signal (the external contact closes) permits scheduled

monitoring after the monitor interval [S Intvl].

Example [2]-1: Input feeding water signal of water softener or other filtration equipment.

When there is a water softener or water treatment equipment has the contact which

turns ON (close) while feeding water, and connecting this contact to the Colormetry,

this remote signal enables scheduled monitoring only while feeding water. When water

stops, and the contact of a water softener or other filtration equipment turns OFF

(open), scheduled monitoring is not performed.

Example [2]-2: Input control signal of motor valve or solenoid valve

When a signal from a motor valve or solenoid valve that controls feeding water, is used

as a remote signal to the Colormetry, it enables monitoring only while the valve is open

and while feeding water.

Example [2]-3: Input supply tank water-level control signal

When a “requesting feed water” signal from the equipment that controls a water level of

a supply tank is used as a remote signal to the Colormetry, monitoring is performed

only for a while the request is made, and while feeding water.

NOTE

It is recommended to input a remote signal if it is possible, to prevent an evaluation error

or a system error. The feeding water signal, if available, should be utilized as the first

priority. If the regeneration signal is the only remote operation signal available from the

water softer, an evaluation error or temperature error may occur from monitoring the

stagnant water while the water is stopped, or a system error may occur due to the lack

of flow. A remote signal input arrangement, as shown in examples [2]-1, [2]-2 and [2]-3 is

highly recommended.

NOTE

If no remote signal is input, be sure to set to the OFF state [S Rte Sgl OFF] (the factory

setting).

SECTION 4 OPERATION

27

2.1.3 Delay time of remote signals

The purpose of remote signal delay time [S DelayTime]:

The setting determines the number of seconds the monitoring (filling with the sample

water) is to be delayed after receiving the remote signal. It is not commonly used

function, however it is effective to prevent an evaluation error in the example case

shown below.

Example of delay:

It is recommended that the sample water for the Colormetry should be taken off as

close to the main piping. However, in a case as illustrated below, where the sample

water is taken off from the secondary line of a motor valve or the valve required a

certain amount of time to open fully, the valve might not open at the time the

Colormetry received the remote signal from the water softer. A wash flow error [Wash

Flow F] may occur due to insufficient sample water pressure.

2.2 Colormetry Monitor Timing

2.2.1 Automatic monitoring

The interval between monitoring is set in the monitor interval [S Intvl] setting at the setting

mode [Set Mode] (The interval is selectable in 30minutes increments between the 30 to 240

minutes range).

The initial time point of monitor interval [S Intvl] is the first monitoring which carried out soon

after the Colormetry is supplied the power or is reset. The next monitoring will start after the

preset time of the monitor interval [S Intvl] from this initial time point.

If the monitor interval [S Intvl] setting is changed, the initial time point is also changed to the

monitoring soon before the change is made. And the monitoring will start after the new

setting time from the last monitoring.

[1] Without remote signal input

Monitoring is performed periodically at the monitor interval [S Intvl].

[2] With remote signal input

a. If the remote signal setting is for “monitoring is enabled by remote signal being

turned OFF” [S Rte Sgl OFF]:

(Example of remote signal: Regeneration signal from water softener equipment)

When the preset time of the monitor interval[S Intvl] has passed, if the remote signal

is OFF, the remote signal delay time [S Rte Sgl dl] will start. If the remote signal is

continuously OFF while preset remote signal delay time, monitoring will start soon

after the remote signal delay time is finished.

When the preset time of the monitor interval [S Intvl] has passed, if the remote signal

is ON, the Colormetry keeps in standby until the remote signal is change back to OFF.

When the remote signal is back to OFF, the preset remote signal delay time [S Rte

Sgl dl] will start. If the remote signal is continuously OFF while preset remote signal

delay time, monitoring will start soon after the remote signal delay time is finished.

Precautions on operation with remote signal input

If the remote signal turns to disabling monitoring in middle of monitoring process, the

monitoring process will still be carried out to completion. However, the verification of

monitoring result is different by which state of monitoring when the remote signal is

received by the Colormetry

In case the remote signal turns to disable monitoring after water discharging from the

drain-water tube is complete and drainage is stopped by the solenoid valve in the

Colormetry is closed, the monitoring result will remain valid.

In case the remote signal turns before water discharge from the drain-water tube

completed and the solenoid valve is still open, the monitoring result will be processed as

follow:

a. If the concentration is evaluated as being lower than the alarm set point:

The result will remain valid and will be displayed as usual.

b. If the concentration is evaluated as being the alarm set point and up:

The evaluation will be invalidated and the previous result will be displayed.

Monitoring is disabled under the following conditions:

When the remote signal is turned OFF while the remote signal setting is [S Rte Sgl ON].

When the remote signal is turned ON while the remote signal setting is [S Rte Sgl OFF].

SECTION 4 OPERATION

[3] With monitor start time [S Start] and stop time [S Stop] are set up

a. When the preset time of the monitor interval [S Intvl] has passed, but not monitor start

time [S Start] yet, the Colormetry keeps in standby until the monitor start time. When

the monitor start time came, the preset remote signal delay time will start and

monitoring will start soon after the remote signal delay time is finished.

b. Without a remote signal input, monitoring will be performed at Monitor interval [S Intvl]

only during the period between Monitor start time [S Start] and stop time [S Stop].

c. With a remote signal input, monitoring will be performed in the same manner as in

paragraph [2] with remote signal input, only during the period between the monitor start

time [S Start] and stop time [S Stop].

NOTE

If the remote signal setting is for “monitoring is enabled by remote signal being turned

ON” [S Rte Sgl ON], periodically check the remote signal.

If no remote signal is available due to a malfunction, the monitoring process will never

start.

2.2.2 Manual monitoring

Press the manual monitor switch to monitor regardless of the monitor interval, remote signal,

monitor start or stop time settings.

(The monitoring will not start, if the reagent cartridge is not installed. The Colormetry may

start the self check on a system error.)

SECTION 4 OPERATION

2.3 Concentration Evaluation

The Colormetry evaluates ionic concentrations in 5 levels: 0mg/L, 1mg/L, 2mg/L, 3mg/L, and

5mg/l.

Alarm set point may be set to trigger at 1mg/L and up, 2mg/L and up, 3mg/L and up and 5mg/L

and up.

NOTE

For boiler use, select 1mg/L or 2mg/L as the alarm set point or follow the equipment in the

boiler.

2.3.1 Manual monitor

If a monitoring result is below the Alarm set point [S AlarmSet], as set in Setting mode [Set

Mode], it will be evaluated as normal. The result of such evaluation will be displayed and

monitoring is complete.

2.3.2 Concentration anomaly

[1] If an evaluation result is the alarm set point [S AlarmSet] and up, monitoring is repeated

the number of times as set (between 1 to 3) in the concentration anomaly retry [S Alarm

Inc No] setting. If all retry results have been the alarm set point [S AlarmSet] and up, only

then, the monitor result will be determined as concentration anomaly.

If, on the other hand, a retry results become to lower than the alarm set point [S

AlarmSet] setting, the condition will be determined to be normal and monitoring will be

finished.

[2] However, an anomaly evaluation made in step [1] alone would not trigger a high

concentration anomaly alarm (that is, to sound buzzer and close the remote alarm output

contact).

In addition, such an anomaly evaluation must be repeated in a series of monitoring at a

preset interval [S Intvl] for a number of times. The response alarm cycle [S Alarm Det No]

is set the number of times(selectable between 1 to 8 times). When all of these monitoring

results indicate a concentration anomaly, it is finally evaluated that a concentration

anomaly exists and the alarm is issued.
